SONAX Premium Class Leather Cleaner

It is a dedicated cleaner, not a 2-in-1. SONAX positions it as the clean step that comes before conditioning, and the product listing directs owners to follow it with SONAX Premium Class Leather Care Cream. It removes dirt and oils but does not leave a lasting conditioning film, so a stand-alone conditioner is the intended second step for anyone who wants to nourish the leather after cleaning.

The manufacturer documents it for both smooth and perforated leather, and the foaming dispenser helps here because the foam clings rather than running into the perforations. As with any liquid on perforated seats, dispense the foam onto a microfiber or soft brush first rather than blasting it directly into the holes, then agitate and wipe. It is not intended for suede or aniline (unfinished) leather.

Denim dye transfer, sometimes called blue-jean transfer, is one of the soiling types SONAX names for this product, and the foaming formula with light brush agitation handles fresh-to-moderate transfer on finished leather. Dye that has been ground in for weeks is harder and may need a second pass. Work in sections and avoid over-scrubbing light nappa.

The SDS discloses a pH of 9.5 to 10.0, which is mildly alkaline rather than pH-neutral. Mild alkalinity is common for cleaners that lift oils, but it is the reason SONAX prescribes a follow-up conditioning step: cleaning then conditioning is the documented two-part system. Used as directed and not left to dwell, it has no widespread community reports of drying or color lift on standard OEM leather.

No. The Amazon listing shows no Prop 65 warning, and the SDS §15 does not list any Prop 65 substances. None of the disclosed ingredients (potassium oleate, glycerol, ethanol) appear on the Prop 65 list. The SDS also classifies the mixture as not classified under GB CLP, with no signal word or hazard statements at the product level.
